Heavy fume smell while car is idealing

Hi there. Check the ignition system to see if the spark plugs have wet fuel on them. If they have fuel on them, then check to see if the spark plug wires are good and have any burn spots. Check to see if the ignition coil it producing any voltage. If the ignition system is good, then check the injectors. The injectors could be leaking and making extra fuel go into the combustion chamber, which then will blow into the exhaust system. Replace any parts that you find not working. If you need further assistance with the fuel exhaust smell when the vehicle is at idle, then seek out a professional, such as one from Your Mechanic, to help you.
